Janet Jackson's brother Randy Jackson has been by her side since she filed for divorce from her husband Wissam Al Mana.

Now in a startling new interview Randy says Janet's husband was verbally abusive to her during their marriage.

In Randy's explosive tell all about Janet's marriage, he said she was verbally abused by billionaire businessman Al Mana, 42, while she was pregnant.

Speaking to People, Randy, 55, claims his sister was degraded and that she was 'called a b**** everyday' while she was pregnant with Al Mana's son. The pair married in 2012, Janet, 51, gave birth to their son Eissa on Jan. 3.

'It was quite an abusive situation,' Randy says of pop star's relationship to Al Mana. He also says that although things never escalated to physical abuse, he did feel at one point he had to intervene.

'I told her, ''You've got to move in with me or I'm going to go over there and there's going to be hell.'' She was really pissed off. I told her, 'I don't care anymore. I'm tired of it. It's too much,' Randy told People.

Randy also claims things changed as his sister's relationship progressed with Al Mana. 'It came on later in the relationship, verbal abuse and being [like] a prisoner in her own home. That's what she went through.'

'There's a lot of pain. Janet's been through a lot with her divorce. I've been through a lot, we all have,' says Randy.

Staying strong: Janet was overcome as she belted out the lyrics, which include: 'What about all the s**t you've done to me? / What about the times you hit my face?' and told fans 'This is me'

The songstress's older brother has been a steady presence at her divorce hearings from Al Mana, which have been in London courts since April.

Randy told People that the family matriarch Katherine Jackson, 87, and their sister Rebbie Jackson, 67, also came out to London from the US to show Janet support during her ongoing divorce.

'I didn't want them to know. My parents are up there in age so I wanted to protect them as much as possible, but now they know,' Randy said of their mother and their father Joe Jackson, 89. Adding now, 'Everybody in the family knows.'

In a statement released to the DailyMail.com a spokesman for Al Mana says: 'Mr Al Mana is not going to dignify these particular and deeply hurtful allegations with a response. The breakdown of his marriage to Janet Jackson is a cause of great sadness to Mr Al Mana, and it is the wellbeing and privacy of their son, Eissa, that remains his sole focus.'

The Toyota Center, where the concert took place, revealed via Twitter that Janet would be donating proceeds from the gig to hurricane relief efforts.

It was also the same day that a lawsuit against Jackson and Live Nation entertainment over a series of cancelled concerts in 2016 was revealed to be settled by TMZ.

The settlement, in which fans received an undisclosed amount for the postponement of her tour after she became pregnant with son Eissa, is one legal worry off of Janet's plate as she sorts out her divorce from billionaire ex-husband Wissam Al Mana.
